It complains about %ps leaking the pointer if kallsym is switched off.
This isn't unique to can and I pointed this out to Kees. 
Oliver Hartkopp mentioned that he wanted to rework the can output.

I'm going to tell vsprintf to route the %ps output the same as %p for
!kallsym so this goes away. 

Depending on what you prefer we can keep it as it or I drop the can bits
and repost everything else as-it. And then address later the other
sashiko bits where the documentation mentions "location of socket in
memory".
